Batman: Arkham Asylum is almost upon us, so publishers Warner Bros. have stepped up their love affair with all things PlayStation with the announcement of a special, Bat-themed tie-in with PlayStation Home.

Anyone purchasing the game on PS3 will be given a free unlock for PlayStation Home, giving them the option of decking out their apartment to look like the Batcave. And not Dark Knight's "office space" batcave, either, a proper, dingy batcave.

The game's out on PS3 on August 25, with the batcave unlockable as quickly as you can get your copy home and download it.

Quick, To The Batcave, PlayStation Home!
